A hadron (pronounced hay-dron, and based upon the Greek hadr=strong) is a composite particle subject to the strong nuclear force (and possibly to weak and electromagnetic forces too), such as a meson (a quark and an antiquark paired in various ways), proton (two up quarks and one down quark), or a neutron (two down quarks and one up quark).[1][2] In general, hadrons are particles made up of quarks, antiquarks, and gluons. They are described by quantum chromodynamics.[3]
